You can download Firefox in the language that you want: http://www.mozilla.org/en-US/firefox/all/
Or you can install Language Packs: https://support.mozilla.org/en-US/kb/use-firefox-interface-other-languages-language-pack
Is this about changing the language for the user interface or about languages used by webpages or about spell check dictionaries or something else ?
Is this about using Firefox from the Mozilla server or about Firefox from the repositories of your Linux distro ?
